DETAILED DESCRIPTION

With the development of wireless communication technologies, theperformance such as transmission rate, delay, throughput, andreliability of wireless communication systems have been greatly improvedthrough technologies such as operation in high-frequency bands (e.g., mmwave), large bandwidths, and multiple antennas. At the same time, thepower consumption of the user terminal (UE, or wireless device, orwireless node) will affect the user experience.

Embodiments of the disclosed technology are directed to reducing UEpower consumption in a wireless communication system while maintainingsystem performance. In an example, a physical downlink control channel(PDCCH) can be configured to carry power-saving information orindications.

In some embodiments, UE power saving methods may include time-domainpower saving techniques, frequency-domain power saving techniques, andspatial power saving techniques. When the UE is in different states,different power saving techniques may be employed or differentindication signaling may be received.

Discontinuous reception (DRX) is a method that is employed in variouswireless technologies to allow the device to turn its receiver offduring periods of inactivity. UEs can be configured to use DRX, wherethe UE can turn its radio frequency (RF) chain on sporadically. WithoutDRX configured, the UE would need to monitor the physical downlinkcontrol channel (PDCCH) according to search space configuration, thatis, keep its RF chain constantly on, resulting in high powerconsumption.

In an example, different signaling or indication may be used when the UEis in a DRX-off period as compared to the case where DRX may not beconfigured or when UE is in Active Time or DRX-on period.

FIG. 1 shows an example of a wireless communication system (e.g., anLTE, 5G or New Radio (NR) cellular network) that includes a BS 120 andone or more user equipment (UE) 111, 112 and 113. In some embodiments,the downlink transmissions (141, 142, 143) include downlink controlinformation (DCI) that include one or more indications that are selectedbased on the state of the respective UE. The UEs perform subsequentcommunications (131, 132, 133) based on its state (e.g., DRX-on,DRX-off, DRX is not configured, or DRX Active Time). The UE may be, forexample, a smartphone, a tablet, a mobile computer, a machine to machine(M2M) device, a terminal, a mobile device, an Internet of Things (IoT)device, and so on.

The present document uses section headings and sub-headings forfacilitating easy understanding and not for limiting the scope of thedisclosed techniques and embodiments to certain sections. Accordingly,embodiments disclosed in different sections can be used or combined witheach other. Furthermore, the present document uses examples from the3GPP New Radio (NR) network architecture and 5G protocol only tofacilitate understanding and the disclosed techniques and embodimentsmay be practiced in other wireless systems that use differentcommunication protocols than the 3GPP protocols.

Example Implementations and Wireless Device States

In some embodiments, a wireless device (e.g., the UE) may be configuredto use discontinuous reception (DRX), which results in the UE being in aDRX-on state or a DRX-off state. On the other hand, a UE may not beconfigured with DRX.

In an example, when DRX is configured, the Active Time (of the DRXcycle) at least includes the time while:

-   -   drx-onDurationTimer or drx-InactivityTimer or        drx-RetransmissionTimerDL or drx-RetransmissionTimerUL or        ra-ContentionResolutionTimer is running; or    -   a Scheduling Request is sent on PUCCH and is pending; or    -   a PDCCH indicating a new transmission addressed to the Cell        Radio Network Temporary Identifier (C-RNTI) of the MAC entity        has not been received after successful reception of a Random        Access Response for the Random Access Preamble not selected by        the MAC entity among the contention-based Random Access        Preamble.

In some embodiments, a wakeup indication includes either a “wake up”indication and/or a “do not wake up” indication. In an example, a “wakeup” indication represents at least one of the following:

-   -   The drx-onDurationTimer needs to be started or restarted in N        DRX cycles, or    -   The UE needs to monitor the first type of DCI set during the        drx-onDurationTimer timing in the N DRX cycles, or    -   The UE needs to monitor the PDCCH during the drx-onDurationTimer        is running in the N DRX cycles, or    -   The UE needs to monitor the first type of DCI set in the N DRX        cycles, or    -   The UE needs to monitor the PDCCH in the N DRX cycles, or    -   The drx-onDurationTimer of N long DRX cycles needs to be started        or restarted, or    -   The UE needs to monitor the PDCCH during the drx-onDurationTimer        of N long DRX cycles is running, or    -   While the drx-onDurationTimer of N long DRX cycles is running,        the UE needs to monitor the first type of DCI set.

In another example, the “do not wake up” indication represents at leastone of the following:

-   -   The drx-onDurationTimer does not need to be started or restarted        during N DRX cycles, or    -   While the drx-onDurationTimer in N DRX cycles is running, the UE        does not need to monitor the first type of DCI set, or    -   While the drx-onDurationTimer in N DRX cycles is running, the UE        does not need to monitor the PDCCH, or    -   The UE does not need to monitor the first type of DCI set in the        N DRX cycles, or    -   The UE does not need to monitor the PDCCH in the N DRX cycles,        or    -   The drx-onDurationTimer of N long DRX cycles does not need to be        started or restarted, or    -   While the drx-onDurationTimer of N long DRX cycles is running,        the UE does not need to monitor the first type of DCI set, or    -   While the drx-onDurationTimer of N long DRX cycles is running,        the UE needs to monitor the PDCCH.

In the above examples, N is a positive integer. In the above examples,the N DRX periods are N DRX periods after the monitoring occasion ofwakeup indication.

Examples of Downlink Control Information (DCI) Embodiments

Downlink control information (DCI) is a information which schedules adownlink data channel (e.g., PDSCH) or an uplink data channel (e.g.,PUSCH). In some examples, the DCI is of different types based on whetheran uplink or a downlink is being scheduled, for either one or multiplecells. In some examples, the DCI is of different types based on thescrambling sequence or scrambled method. In some examples, the DCI is ofdifferent types based on the search space. In some examples, the DCI isof different types based on the control resource set (CORESET). In someexamples, the DCI is of different types based on the RNTI (radio networktemporary identity) type.

In some embodiments, the first type of DCI set is related to at leastone of the RNTI that scrambles the DCI, the search space, the controlresource set (CORESET) and the subcarrier spacing.

In some embodiments, the first type of DCI set includes at least one ofthe following characteristics or features:

-   -   Scrambled by C-RNTI, CS-RNTI, MCS-C-RNTI, SP-CSI-RNTI, SFI-RNTI,        INT-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, or TPC-SRS-RNTI DCI.    -   Includes at least a DCI of the UE-specific search space.    -   Includes at least a DCI scrambled by a C-RNTI, a CS-RNTI, an        MCS-C-RNTI, or an SP-CSI-RNTI.    -   Does not include a DCI whose CORESET is CORESET zero.    -   Does not include a DCI whose search space is search space zero.    -   Does not include DCI scrambled by TC-RNTI, SI-RNTI, RA-RNTI,        PS-RNTI, or P-RNTI.    -   Does not include TC-RNTI, SI-RNTI, RA-RNTI, PS-RNTI, P-RNTI,        SFI-RNTI, INT-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, or        TCI-SRS-RNTI scrambled DCI.

In some embodiments, the first type of DCI set does not include thesecond type of DCI set.

In some embodiments, the second type of DCI set is related to at leastone of the RNTI that scrambles the DCI, the search space, the controlresource set (CORESET) and the subcarrier spacing.

In some embodiments, the second type of DCI set includes at least one ofthe following characteristics or features:

-   -   Includes at least a DCI in which the search space is a common        search space.    -   Includes at least a DCI that is a Type 0-PDCCH common search        space set.    -   Includes at least a DCI that is a Type0A-PDCCH common search        space set.    -   Includes at least a DCI that is a Type 1-PDCCH common search        space set.    -   Includes at least a DCI that is a Type 2 PDCCH common search        space set.    -   Includes a DCI whose CORESET is CORESET zero.    -   Includes a DCI whose search space is search space zeros.    -   Scrambled by TC-RNTI, SI-RNTI, RA-RNTI, PS-RNTI, or P-RNTI.    -   Includes TC-RNTI, SI-RNTI, RA-RNTI, PS-RNTI, P-RNTI, SFI-RNTI,        INT-RNTI, TPC-PUCCH-RNTI, TPC-PUSCH-RNTI, or TCI-SRS-RNTI        scrambled DCI.

In some embodiments, the PS-RNTI can be used for power saving of the UE,or the PS-RNTI is used to scramble the first signaling or the secondsignaling (e.g., different indications that are transmitted based on thestate of the UE). In other embodiments, the PS-RNTI scrambled DCI maycarry a wake-up indication. In some examples, the second type of DCI setmay include

-   -   DCI scrambled by the TC-RNTI, or    -   DCI scrambled by the SI-RNTI, or    -   DCI scrambled by the RA-RNTI, or    -   DCI scrambled by the PS-RNTI, or    -   DCI scrambled by the PS-RNTI.

In some embodiments, the TC-RNTI (Temporary C-RNTI) can be used for aRACH (random access channel) or a random access procedure, the SI-RNTIis used for a broadcast system message, the RA-RNTI can be used for arandom access response (Random Access Response), and the PS-RNTI is usedto scramble the UE power saving information. If the UE does not monitorall or part of the RNTI scrambled DCI for a long period of time, theperformance and latency of the communication system may be seriouslyaffected. Therefore, the wakeup indication does not affect UE'sactivities of monitoring the TC-RNTI, the SI-RNTI, the RA-RNTI, orPS-RNTI scrambled DCI. Furthermore, the wake-up indication does notaffect the UE's activities of monitoring the second type of DCI set.

In some embodiments, the wakeup indication may be carried by the secondsignaling.

Examples of Time-Domain Resource Allocation Embodiments

In some embodiments, the offset of a time-domain resource allocationindication includes at least one of a minimum timeoffset K0, a minimumtime offset K1, a minimum time offset K2, a minimum aperiodic CSI-RSoffset, and a minimum aperiodic SRS offset.

For example,

-   -   The time offset K0 represents a slot offset between the DCI and        its scheduled PDSCH    -   The time offset K2 represents a slot offset between the DCI and        its scheduled PUSCH    -   The time offset K1 represents a slot offset between the PDSCH        and its HARQ-ACK feedback    -   The aperiodic CSI-RS offset represents a slot offset between a        DCI including a triggering aperiodic CSI-RS resource set and a        triggered aperiodic CSI-RS resource set    -   The aperiodic SRS offset represents a slot offset between a DCI        that includes a triggering aperiodic SRS resource set and a set        of aperiodic SRS resources

In some embodiments, the minimum time-domain resource offset indicationmay be carried by the first signaling. In other embodiments, the minimumtime-domain resource offset indication may be carried by the secondsignaling.

Examples of Bandwidth Part (BWP) Embodiments

Bandwidth parts (BWPs) enable more flexibility in how resources areassigned in a given carrier. For example, bandwidth parts enablemultiplexing of different signals and signal types for betterutilization and adaptation of spectrum and UE power.

In some embodiments, signaling BWP information includes the state(s) ofthe bandwidth part. In some embodiments, the states includes an activestate, an inactive state, or a dormant state. In some embodiments, thestates includes an active state or a dormant state. In some embodiments,the states includes an inactive state or a dormant state.

Bandwidth part indicator. In some embodiments, the indicator indicatesthe active bandwidth part (Active BWP). In some embodiments, theindicator indicates the dormant bandwidth part (BWP).

In some embodiments, the BWP indication may be carried by the firstsignaling or the second signaling.

Example 1. In some embodiments, if the UE receives or detects the firstor second signaling indication, or before the first or second signalingis valid, if the condition A-1 is met, the first or second signalingtriggers or activates a reference signal resource set or reportingresource configuration.

In other embodiments, the first or second signaling triggers oractivates a reference signal resource set or reporting resourceconfiguration.

In some embodiments, the first or second signaling includes BWPinformation. The BWP information includes switching to a dormant BWP orswitching to a BWP dormant state.

In this example, the condition A-1 satisfies at least one of thefollowing:

-   -   The periodic CSI-RS is not configured on the dormant or target        BWP or the active BWP,    -   No periodic CSI report is configured on the dormant or target        BWP or the active BWP,    -   No semi-persistent CSI-RS is configured or activated on the        dormant BWP or the target BWP or the active BWP, or    -   No semi-persistent CSI reporting is configured or activated on        the dormant BWP or the target BWP or the active BWP.

In some embodiments, if the condition A-1 is met, the first signaling orthe second signaling triggers or activates the CSI reporting. Herein,the time domain behavior of CSI reporting is semi-persistent.

In some embodiments, if the condition A-1 is met, the first signaling orthe second signaling triggers or activates the CSI-RS set. Herein, thetime domain behavior of CSI-RS set is semi-persistent.

In some embodiments, the CSI reporting mode is semi-persistent CSIreporting.

In some embodiments, the CSI-RS resource set is a semi-persistent CSI-RSresource set.

In some embodiments, the DCI carrying the second signaling is scrambledby the PS-RNTI.

In some embodiments, the DCI carrying the first signaling is scrambledby the SP-CSI-RNTI. In other embodiments, the DCI carrying the firstsignaling is an uplink scheduling DCI.

In some embodiments, if the UE has an active periodic CSI-RS/CSI-IMresource configuration, if the corresponding activated BWP is switchedto the dormant state, the resource configuration is still active.

In some embodiments, if the UE has or an active periodic ZP CSI-RSresource set configuration, if the corresponding activated BWP isswitched to the dormant state, the resource configuration is stillactive.

By configuring periodic or semi-persistent CSI measurement and reportingin the dormant BWP or the dormant state, the PDCCH monitoring powerconsumption on the serving cell can be reduced, and UE can quicklyswitches to the active BWP or active state to receive or transmits data.

In some embodiments, if part of the bandwidth information indicated bythe first or second signaling includes switching to a dormant BWP orswitching to a BWP dormant state, the UE may ignore a part of theinformation field in the first or second signaling indication.

In some embodiments, if part of the bandwidth information indicated bythe first or second signaling includes switching to a dormant BWP orswitching to a BWP dormant state, part of information fields in thefirst or second signaling indication is the all zeros or all 1's state.

In some embodiments, a part of the information field of the firstsignaling or the second signaling indication is a specific state, andthe BWP corresponding to the BWP indicator is indicated as a dormantstate. In an example, the specific state is the all 0 or the all 1state.

In some embodiments, the part of the information field of the first orsecond signaling indication includes a redundancy version of theinformation field, a modulating and coding scheme (MCS) informationfield, or frequency resource domain assignment information field.

In some embodiments, the indication information in the first signalingor the second signaling is for one of the following operations:

-   -   Switch to a dormant BWP or switch to a BWP dormant state;    -   Switch out of the dormant BWP or switch out of the BWP dormant        state;    -   Switch the BWP from dormant state to the active state.

In these examples, the BWP indication information in the first signalingor the second signaling is applicable to uplink and downlink operations.In these examples, the uplink and downlink operations are bundled.

In some embodiments, if the indication information in the firstsignaling or the second signaling includes switching to the dormant BWP,UE switches to the dormant BWP for both the uplink and the downlinkoperation. The uplink dormant BWP and the downlink dormant BWP have oneof the following characteristics: the same ID, a BWP having a minimum IDor an ID of 0.

In some embodiments, if the indication information in the firstsignaling or the second signaling includes switching to the BWP dormantstate, UE switches both the uplink BWP and the downlink BWP to a dormantstate.

In some embodiments, if the indication information in the firstsignaling or the second signaling includes switching out of the dormantBWP, UE switches both the uplink and the downlink switch out of thedormant BWP. Among them, UE switches the uplink BWP to the BWP whose IDis firstActiveUplinkBWP-Id or 0 or the minimum value. UE switches thedownlink BWP to the BWP whose ID is firstActiveDownlinkBWP-Id or 0 orthe minimum value. Alternatively, UE switches the uplink and downlinkBWP to the most recently activated non-dormant BWP. Alternatively, UEswitches the uplink and downlink BWP to the BWP with the largest ID.

In some embodiments, if the indication information in the firstsignaling or the second signaling includes switching out of the BWPdormant state, or switching the BWP from dormant state to the activestate, UE switches both the uplink and uplink BWPs to the active state.

Example of MIMO Layer Embodiments

Embodiments of the disclosed technology support massive multiple-inputmultiple-output (MIMO) operation, which can significantly increase thesystem throughput. Massive MIMO can support multiple MIMO layers, eachof which is a data stream that is assigned to a user with the layersbeing orthogonally separated in the space domain (with pre-codingensuring that there is no cross-layer interference).

In some embodiments, the MIMO layer information includes one or more ofthe following:

The maximum MIMO layer indication that indicates the maximum number ofMIMO layers used to transmit PDSCH or PUSCH. In some embodiments, themaximum number of MIMO layers is the layer that the UE does not expectto receive the PDSCH or transmit the PUSCH.

Example 1. In some embodiments, the maximum MIMO layer is indicated by abandwidth part indication. In some example, each BWP or at least one BWPcould be configured with a maximum MIMO layer. Adaptation of the maximumMIMO layer can be implemented via BWP switching.

For example, the configuration information of the UE includes at leastone of a first type of maximum MIMO layer, and/or a second type ofmaximum MIMO layer. The first type of maximum MIMO layer (for example,L1_D and/or L1_U) is a cell specific parameter. The second type ofmaximum MIMO layer (for example, L2_D and/or L2_U) is a BWP specificparameter.

The cell specific parameter represents that the parameter is applicableto downlink and/or uplink scheduling of all BWPs of the UE in the cell.Alternatively, the cell specific parameter represents that the parameteris applicable to the UE in the downlink and/or uplink scheduling of theBWP of the second type of parameters that are not configured or valid inthe cell. Alternatively, the cell specific parameter represents that theparameter is applicable to downlink and/or uplink scheduling of the BWPother than a first type of BWP of the UE in the cell.

In some embodiments, the BWP specific parameter represents that theparameter is applicable to downlink and/or uplink scheduling of the UEin the BWP in which the second parameter is configured or valid or afirst type of BWP. In some embodiments, the BWP specific parameterindicates that the parameter is applicable to downlink and/or uplinkscheduling of the UE in the BWP.

In some embodiments, the first type of maximum MIMO layer L1_D isapplicable to downlink scheduling of all BWPs of the UE in the cell.Alternatively, the first type of maximum MIMO layer L1_D is applicableto BWP in which the second type of parameters are not configured orvalid of the UE in the cell. Alternatively, the first type of themaximum MIMO layer L1_D is applicable to the downlink scheduling of theBWP of the UE other than the first type of BWP in the cell.

In some embodiments, the second type of maximum MIMO layer L2_D isapplicable to downlink scheduling of the UE in the BWP in which thesecond type of maximum MIMO layer L2_D is configured or valid or a firsttype of BWP. In some embodiments, the second type of maximum MIMO layerL2_D is applicable to downlink and/or uplink scheduling of the UE in theBWP.

In some embodiments, the first type of maximum MIMO layer L1_U isapplicable to uplink scheduling of all BWPs of the UE in the cell, orthe first type of maximum MIMO layer L1_U is applicable to BWP of whichthe second type of parameters is not configured or valid. In someembodiments, the maximum MIMO layer L1_U of the first type is applicableto the uplink scheduling of the BWP of the UE other than a first type ofBWP in the cell.

In some embodiments, the second type of maximum MIMO layer L2_U isapplicable to uplink scheduling of the UE in the BWP in which the secondtype of maximum MIMO layer L2_U is configured or valid or a first typeof BWP. In some embodiments, the second type of maximum MIMO layer L2_Uis applicable to downlink and/or uplink scheduling of the UE in the BWP.

In these examples, the first type of BWP includes at least one of adefault BWP, an initial BWP, a BWP with the minimum ID or a dormant BWP.

The dormant BWP includes at least one of the following features:

-   -   no need to monitor the PDCCH,    -   need to measure CSI,    -   need to perform beam management, or    -   no need for uplink or downlink data transmission.

In some embodiments, the UE does not expect the second type of maximumMIMO layer L2_D to be greater than the first type of maximum MIMO layerL1_D.

In some embodiments, if the second type of maximum MIMO layer L2_D isnot configured, then the number of PDSCH scheduling layers of all BWPsin the cell cannot exceed the first type of maximum MIMO layer L1_D.

In some embodiments, if the first type of maximum MIMO layer L1_D is notconfigured, and if the second type of maximum MIMO layer L2_D isconfigured on the first type of BWP, then the number of layers of thePDSCH scheduling in the first type of BWP cannot exceed the second typeof maximum MIMO layer indication L2_D.

In some embodiments, if the first type of the maximum MIMO layer L1_D isconfigured, and if the second type of the maximum MIMO layer L2_D isconfigured on the first type of BWP, then the number of layers of thePDSCH scheduling in the first type of BWP cannot exceed the second typeof maximum MIMO layer L2_D.

In some embodiments, if the second type of the maximum MIMO layer L2_Dis configured on the first BWP, then the number of layers of the PDSCHscheduling in the first type of BWP cannot exceed the second type ofmaximum MIMO layer L2_D.

In some embodiments, if the first type of maximum MIMO layer L1_D andthe second type of maximum MIMO layer indication L2_D are configured,then the number of layers of the PDSCH scheduling in the first type ofBWP cannot exceed the second type of maximum MIMO layer indication L2_D.

In some embodiments, the UE does not expect the second type of maximumMIMO layer L2_U to be greater than the first type of maximum MIMO layerindication L1_U.

In some embodiments, if the second type of maximum MIMO layer indicationL2_U is not configured, then the number of layers of PUSCH scheduling ofall BWPs in the cell may not exceed the first type of maximum MIMO layerindication L1_U.

In some embodiments, if the first type of maximum MIMO layer L1_U is notconfigured, and if the second type of maximum MIMO layer indication L2_Uis configured on the first BWP, then the number of layers of the PUSCHscheduling in the first type of BWP cannot exceed the second type ofmaximum MIMO layer L2_U.

In some embodiments, if the first type of the maximum MIMO layer L1_U isconfigured, and if the second type of the maximum MIMO layer L2_U isconfigured on the first BWP, then the number of layers of the PUSCHscheduling in the first type of BWP cannot exceed the second type ofmaximum MIMO layer indication L2_U.

In some embodiments, if the second type of the maximum MIMO layer L2_Uis configured on the first BWP, then the number of layers of the PUSCHscheduling in the first type of BWP cannot exceed the second type ofmaximum MIMO layer L2_U.

In some embodiments, if the first type of maximum MIMO layer L1_U andthe second type of maximum MIMO layer L2_U are configured, then thenumber of layers of the PUSCH scheduling in the first type of BWP cannotexceed the second type of maximum MIMO layer L2_U.

In some embodiments, for the first type of BWP, if the second type ofmaximum MIMO layer L2_U is configured, then the maximum rank is the sameas the second type of maximum MIMO layer L2_U.

Examples of Interpretation of Bit Fields

In some embodiments, the bit field indication information in the firstor second signaling is related to the other bit field indicationinformation.

For example, the first bit field of the first or second signalingdetermines the information indicated by the second bit field of thefirst or second signaling. For example, if the first bit field is eitherthe first code point or the wakeup, the second bit field indicates theperiod of the wakeup indication.

For another example, if the first bit field of the first or secondsignaling is either a second code point or non-awake information, thesecond bit field indicates the period of the non-wakeup indication.

The following table shows an example relationship between the first bitfield indication information and the second bit field indicationinformation

First bit field Second bit value or code field value or point code pointSecond bit field indication information C1-1 C2-1 The UE needs to wakeup in N_1 DRX cycles; .... .... .... C1-1 C2-n The UE needs wake up inN_n DRX cycles; C1-2 C2-1 The UE does not need to wake up in N_1 DRXcycles; .... .... .... C1-2 C2-n The UE does not need to wake up in N_nDRX cycles; .... .... ....

In the table above, C1-1, C1-2, C2-1, C2-2, N_1, and N_n arenon-negative integers.

For yet another example, the first bit field of the first or secondsignaling is either the first code point or the wake-up information, theinformation indicated by the second bit field of the first or secondsignaling includes at least one of the following: offset of time-domainresource allocation information, bandwidth part indicator information,maximum MIMO layer information or PDCCH monitoring information or RSresource set information.

For yet another example, if the first bit field of the first or secondsignaling is either a second code point or non-awake information, thesecond bit field indication information of the first or second signalingindicates that the drx-onDurationTimer does not need to bestarted/restarted in the N DRX cycles, or the UE does not need tomonitor the first type of DCI set during the drx-onDurationTimer timingin the N DRX cycles; or the UE does not need to monitor PDCCH in the NDRX cycles; or, the UE does not need to monitor the first type of DCIset in N DRX cycles.

In this example, N is a non-negative integer. In some embodiments, N isrelated to the value of the second bit field.

Examples of Signaling in Cells and/or Cell Groups

In some embodiments, the first or second signaling is sent in a firstcell or a cell group. Alternatively, the UE monitors the PDCCH carryingthe first or second signaling only in the first cell or cell group. Thefirst cell or the set of cells may include one of the following: aprimary cell, a special cell (Spcell, special cell), a PScell, or a cellconfigured by a high layer signaling.

In some embodiments, the PDCCH carrying the first or second signaling istransmitted/monitored only in certain specific cells or cell sets, whichcan advantageously save resource overhead and also provide power savinggains.

In some embodiments, the number of DCI lengths or information field bitscarried by the first or second signaling depends on at least one of thefollowing factors:

-   -   Parameter configuration of the first cell or cell set; or    -   number of configured cells or cell sets; or,    -   number of active cells or cell sets; or,    -   The number of predefined bits for all or part of the information        field.

In some embodiments, the number of DCI lengths or information field bitscarried by the first or second signaling depends on the parameterconfiguration of the first cell or the set of cells, or the number ofentries, or the maximum or maximum index in the parameter configurationset. For example, the number of bandwidth parts, the number of entriesin the minimum time domain resource offset set or the maximum or minimumtime domain resource offset set or maximum index, the number of entriesin the maximum MIMO layer set or the maximum MIMO layer or maximumindex, the number of entries in the PDCCH monitoring information set orthe maximum value of the PDCCH monitoring information set or maximumindex.

In some embodiments, the number of DCI lengths or information field bitscarried by the first or second signaling depends on the number ofconfigured cells or cell sets.

In some embodiments, the number of DCI lengths or information field bitscarried by the first or second signaling depends on the number ofactivated cells or cell sets.

In some embodiments, the number of DCI lengths or information field bitscarried by the first or second signaling depends on the predefinednumber of bits of all or part of the information field. For example, thebit length of all or part of the information fields in the DCI ispredefined.

In some embodiments, for a cell or a set of cells, the relevantinformation can be obtained by one of the following:

Method-1: Configure the serving cell ID, the location information in theDCI, and the mapping rule; or

Method-2: Configuring or pre-defining the information of the servingcell and the DCI code point mapping rule; or

Method-3: Modifying the relevant information field according to theconfiguration parameters of the cell or the cell set; or

Method-4: deriving the indicated information of a cell or a set of cellsaccording to the first or second signaling value.

In some embodiments, the second cell or set of cells may be the samecell or a set of cells as the first cell or the set of cells, or a setof cells or cells having the same identification (ID).

In an example for Method-1, the configuration information of the UEincludes: a serving cell or a cell set ID, location information in theDCI, and a mapping rule. The location information includes at least oneof: an information block index, a bit index, a block start position, astart bit position, a block end position, a end bit position, a blocksize, or a number of bits. The UE may be configured with multiple cellor cell set IDs, corresponding location information, and mapping rules,so that the UE acquires corresponding configuration information ofmultiple cells or cell sets.

In an example for Method-2, the information of each cell or cell set isjointly coded. The joint coding method includes that the same type ofinformation of different cells or cell sets is jointly coded; ordifferent types of information of different cells or cell sets arejointly coded. The same type of information of the different cells orcell sets is jointly coded. The same type of information of differentcells or cell sets is represented by the same information field. Thedifferent types of information of the different cells or cell sets arejointly coded. The different types of information of different cells orcell sets are represented by the same information field.

In an example for Method-3, the first or second signaling is sent in afirst cell or a cell group. For the second cell or the cell set, theinterpretation of information or information field carried is one of thefollowing:

-   -   Mod(cell_indicator_1, Max_indicator_2); or,    -   Min(cell_indicator_1, Max_indicator_2); or,    -   Mod(cell_value_1, Max_value_2); or,    -   Min(cell_value_1, Max_value_2); or,    -   Operator-1(cell_value_1, cell_value_set_2); or,    -   Operator-2 (cell_value_1, cell_value_set_2); or,

In an example, if the number of bits of the second cell or the cell setrelated information field is greater than the number of indicatorsindicator_size_1 that characterizes the first cell or the cell setrelated information field, indicator_size_2-indicator_size_1 of zerosare padded before or after the information field for the interpretation.

In another example, if the number of bits indicator_size_2characterizing the second cell or the cell set related information fieldis smaller than the number of bits indicator_size_1 characterizing thefirst cell or the cell set related information field,indicator_size_1-indicator_size_2 bits of the most/least significantbits are truncated for the interpretation.

In the above examples, the cell_indicator_1 is the value/code point ofthe information field, the Max_indicator_2 is the number of resourcesassociated with the information field configured by the second cell orthe cell set, the cell_value_1 is the resource information indicated bythe information field, and the Max_value_2 is a maximum value of theresource associated with the information field configured with thesecond cell or the cell set; cell_value_set_2 is a set of resourcevalues associated with the information field configured for the secondcell or the set of cells; operator-1 (cell_value_1, cell_value_set_2)indicates a minimum value of the cell_value_set_2 that is not less thanthe value of cell_value_1; operator-2(cell_value_1, cell_value_set_2)indicates that the largest value of set cell_value_set_2 is not greaterthan cell_value_1. Among them, the values in cell_value_set_2 arearranged from small to large, or from large to small.

In another example for Method-3, the first or second signaling is sentin a first cell or a cell group. For the second cell or the cell set,the interpretation of information or information field carried is one ofthe following:

-   -   Mod(cell_indicator_s, Max_indicator_2); or,    -   Min(cell_indicator_s, Max_indicator_2); or,    -   Mod(cell_value_s, Max_value_2); or,    -   Min(cell_value_s, Max_value_2); or,    -   Operator-1(cell_value_s, cell_value_set_2); or,    -   Operator-2 (cell_value_s, cell_value_set_2); or,

In an example, if the number of bits indicator_size_2 of the second cellor cell set related information field is greater than the number of bitsof the first or second signaling related information fieldindicator_size_s, (indicator_size_2-indicator_size_s) of zeros arepadded before or after the information field for the interpretation.

In another example, if the number of bits indicator_size_2characterizing the second cell or the cell set related information fieldis smaller than the bit number indicator_size_s of the first or secondsignaling related information field, indicator_size_s-indicator_size_2bits of the most/least significant bits are truncated for theinterpretation.

In the above examples, cell_indicator_s is the value/code point of thefirst or second signaling information field, and Max_value_2 is amaximum value of the resource associated with the information fieldconfigured with the second cell or the cell set; and cell_indicator_s isthe first or second signaling information field indication. Resourceinformation, Max_value_2 is a maximum value of resources related to theinformation field configured by the second cell or the cell set;cell_value_set_2 is a set of resource values related to the informationdomain configured for the second cell or the cell set; operator-1(cell_value_s), cell_value_set_2) indicates that minimum value of theset cell_value_set_2 is not less than cell_value_s; operator-2(cell_value_s, cell_value_set_2) indicates that the largest value of setcell_value_set_2 is not greater than cell_value_s.

In some embodiments, the second cell or set of cells may be the samecell or a set of cells as the first cell or the set of cells, or a setof cells or cells having the same identification mark (ID).

In an example for method-4, the cell or the cell set directly derivesthe corresponding parameter configuration according to the informationindicated by the first or second signaling information field.

Examples of Additional Field Position

In some embodiments, additional bit fields may be added based onpredefined conditions that are related to at least one of the followingfactors: DCI format, location of some information fields in the DCI,search space.

The first predefined condition is that the DCI format of the indicationinformation is DCI format 0_0, or the number of bits after the UL/SULinformation field in the DCI is a fixed length (including 0), or theinformation field bit length after the UL/SUL information field isrelated to only UE specific or cell specific or carrier specificparameter/configuration.

The second predefined condition is that the DCI format of the indicationinformation is DCI format 0_1, or the number of bits before the carrierindicator information field or the UL/SUL information field or thebandwidth part indicator information field in the DCI is a fixed length(including 0). Or, the information field bit length before the carrierindicator information field or the UL/SUL information field or thebandwidth part indicator information field in the DCI in the DCI isrelated to only UE specific or cell specific or carrier specificparameter/configuration.

The third predefined condition is that the DCI format of the indicationinformation is DCI format 1_1, or the number of bits before the carrierindicator information field or the bandwidth part indicator informationfield in the DCI is a fixed length (including 0), or the DCI Theinformation field bit length before the carrier indicator informationfield or the bandwidth part indicator information field in the DCI isrelated to only UE specific or cell specific or carrier specificparameter/configuration.

In some embodiments, the bit field carrying the indication informationmay be at least one of the following information fields are predefinedcode points or a part of bits of at least one of the followinginformation fields:

-   -   Frequency domain resource assignment field;    -   Retransmission process number (HARQ process number) field;    -   Carrier indicator field;    -   Bandwidth part indication (BWP indicator) field;    -   A second transport block (transport block 2) field;    -   Downlink assignment index field;    -   Modulation and coding scheme field;    -   Precoding information and number of layers;    -   Antenna port field;

Example 1. In some embodiments, for the first type of information, thebit field of the indication information includes part or all of the codepoints or part or all bits in the bandwidth part indication field.

For example, the first code point set in the bandwidth part indicationfield indicates a bandwidth part, and the second code point set in thebandwidth part indication field represents the first type ofinformation.

For another example, the first bit set in the bandwidth part indicationfield indicates a bandwidth part, and the second bit set in thebandwidth part indication field represents the first type ofinformation. The first set of bits is a high-order bit or a status bitin the bandwidth part indication field.

For yet another example, if the UE does not support switching the BWPthrough the DCI, the indication of the first type of informationincludes a bandwidth part indication field.

In some embodiments, the first type of information has at least one ofthe following characteristics:

One or more may be configured by higher layer signaling (RRC signalingor MAC CE); or,

The configuration of the first type of information is BWP specific (perBWP).

In some embodiments, the first type of information includes at least oneof a minimum time-domain resource offset or a maximum MIMO layer.

In this example, if the UE does not support switching the BWP throughthe DCI, or the number of configured BWPs is limited, the first type ofinformation can be indicated by the bandwidth part indication field.

Example 2. In some embodiments, for the second type of information, thebit field of the indication information includes some or all code pointsor partial bits or all bits in the downlink allocation index domain.

For an example, the first code point set in the downlink allocationindex field indicates a downlink allocation index, and the second codepoint set in the bandwidth part indication field indicates the secondtype information.

For another example, the first bit set in the downlink allocation indexfield indicates a downlink allocation index, and the second bit set inthe downlink allocation index field indicates second type information.The first set of bits is the most/least significant bits in thebandwidth part indication field.

For yet another example, if the first condition is met, the indicationof the first type of information includes a downlink allocation indexfield; otherwise, the downlink allocation index field indicates adownlink allocation index.

In some embodiments, the downlink allocation index field includes atleast one of the following: a first downlink allocation index field, asecond downlink allocation index field, or a downlink allocation indexfield.

For an example, for the first downlink allocation index field, the firstcondition is to adopt a dynamic HARQ-ACK codebook. If the dynamicHARQ-ACK codebook is used, the first downlink allocation index fieldindicates a codebook; otherwise, the first downlink allocation indexfield includes at least one bit or one code point indicating the secondtype of information.

In some embodiments, for the second downlink allocation index field, thefirst condition is a dynamic HARQ-ACK codebook based on two sub-HARQ-ACKcodebooks (sub-code books). If the dynamic HARQ-ACK codebook is based ontwo sub-HARQ-ACK codes, the first downlink allocation index fieldindicates a codebook; otherwise, the first downlink allocation indexfield includes at least one bit or one code point indicating the secondtype of information (eg, two bits, or four code points);

In some embodiments, for the downlink allocation index field, the firstcondition is that the number of serving cells in the downlinkconfiguration is greater than 1, and is a dynamic HARQ-ACK codebook. Ifthe number of serving cells configured for the downlink is greater than1, and is a dynamic HARQ-ACK codebook, the downlink allocation indexfield indicates a codebook; otherwise, the downlink allocation indexfield includes at least one bit or one code point indicating the secondtwo type of information; (for example, two bits, a high bit of 2 bits,or four code points).

In some embodiments, the second type of information includes at leastone of the following:

-   -   Wake-up indicator;    -   Offset of time domain resource allocation;    -   Bandwidth part indicator;    -   Maximum MIMO layer indication;    -   PDCCH monitoring indication; or,    -   Reference signal resource set indication.

In some embodiments, UE can ignore all or some of fields that do notcontain the second type of information.

In some embodiments, all or some of fields that do not contain thesecond type of information are zeros or ones.

Examples of Multi-Beam Operation

In some embodiments, the monitoring occasion of the second signalingdoes not include a DRX Active Time, during which the beam managementmechanism fails to work, and the first and/or second transmitting nodes(UE and/or base station, UE and/or TRP) may lose the beam pairinformation. In order to improve the reliability of the secondsignaling, in a multi-beam operation, the base station can repeatedlytransmit the same information content with multi-beams. The UE can softcombine the energy of multiple beams to improve decoding performance. Onthe other hand, considering the encoding method of the second signaling(for example, a Polar code encoding), the first signaling that isrepeatedly transmitted should be the same bit length after the operationof encoding/rate matching or the first signaling that is repeatedlytransmitted. Alternatively, the same aggregation level may be used orthe same resource element (RE) number occupied.

For an example, in the case of multiple beams, the signaling transmittedin the multiple beams should contain the same information and use thesame aggregation level or occupy the same RE number or the same bitafter encoding/rate matching.

For another example, in the case of multiple beams, the signalingtransmitted in the multiple beams should contain same information, andthe number of aggregation levels is not less than 8.

For another example, in the case of multiple monitoring occasions, theUE expects to receive the signaling of different monitoring occasionswith same information and the same aggregation level or occupy the sameRE number or coded bits.

For another example, in the case of multiple monitoring occasions, theUE expects to receive the signaling of different monitoring occasionswith same information, and the number of aggregation levels is not lessthan 8.

For another example, in the case of multiple monitoring occasions, theUE expects to receive the DCI of different monitoring occasions withsame information and the same aggregation level or occupy the same REnumber or coded bits.

For another example, in the case of multiple monitoring occasions, theUE expects to receive the DCI of different monitoring occasions withsame information, and the number of aggregation levels is not less than8.

Example 1. In some embodiments, the DCI carrying the second signalingincludes a wakeup indication. The configuration information of the UEincludes a serving cell ID, and the wakeup indicates locationinformation in the DCI. If the UE is configured with multi-carrieroperation (CA, DC, SUL, or SDL), the wake-up indication of differentcarriers are bitmapped into the DCI.

As shown in FIG. 3, the UE configures serving cells cell-i and cell-j.

For the serving cell cell-i, the configuration information of the UEincludes Cell ID cell-i-ID. In an example, the configuration informationof the UE includes location information of the wake-up of cell-i in theDCI.

In some embodiments, the UE monitors the DCI carrying the secondsignaling in a specific cell. The specific cell may be a Pcell, aPScell, a Spcell, or a cell configured with search space of secondsignaling.

In some embodiments, the location information may be a bit location or abit block location.

In some embodiments, the location information includes at least one of astarting bit position, an end bit position, a bit length, a startingposition of a block, a bit block index, or an end position of a block.

TABLE 1 Bi Wake up indication State 1 Wake State 2 Not wake up

For example, as in Table 2, Bi is a bit block. Herein, one bit of Bi(eg, Bi-0) is a wake-up indication, and other bits (eg, Bi-others)indicate a time period that the wake-up indication is valid orindicated. When Bi-0 indicates “wake-up”, Bi-others indicates the timeperiod that the corresponding wake-up is valid or indicated. when Bi-0indicates “do not wake-up”, the Bi-others indication indicates timeperiod that the corresponding non-wake-up is valid or indicated,

TABLE 2 Bi-0 Bi-others Instructions Status 1 Bi-1 The UE needs to wakeup in N_1 DRX cycles; .... .... .... Status 1 Bi-n The UE needs to wakeup in N_n DRX cycles; Status 2 Bi-1 The UE does not need to wake up inN_1 DRX cycles; .... .... .... Status 2 Bi-n The UE does not need towake up in N_n DRX cycles;

Example 2. In some embodiments, the DCI carrying the second signalingincludes a wakeup indication.

In some embodiments, the configuration information of the UE includeslocation information of waking up indication in the DCI.

In some embodiments, the wakeup indication applies to all serving cellsor activated serving cells.

As shown in FIG. 2, the configuration information of the UE includeslocation information of waking up indication in the DCI.

In some embodiments, the location information may be a bit location or abit block location.

In some embodiments, the location information includes at least one of astarting bit position, a end bit position, a bit length, a startingposition of block, a bit block index, or an end position of block.

For example, in Table 3, if Bi is state 1 (for example, 1), it indicates“wake up”; if Bi is state 2 (for example, 0), it indicates “do not wakeup”.

TABLE 3 Bi Wake up indication Status 1 Wake Status 2 Not wake up

For example, in Table 4, Bi is a bit block. Herein one bit of Bi (e.g.,Bi-0) is a wake-up indication, and other bits (e.g., Bi-others) indicatea time period that the wake-up indication is valid or indicated. WhenBi-0 indicates “wake-up”, Bi-others indicates the time period that thecorresponding wake-up is valid or indicate. when Bi-0 indicates “nowake-up”, the Bi-others indication indicates time period that thecorresponding non-wake-up is valid or indicated,

TABLE 4 Bi-0 Bi-others Instructions Status 1 Bi-1 The UE needs to wakeup in N_1 DRX cycles; .... .... .... Status 1 Bi-n The UE needs to wakeup in N_n DRX cycles; Status 2 Bi-1 The UE does not need to wake up inN_1 DRX cycles; .... .... .... Status 2 Bi-n UE does not need to wake upin N_n DRX cycles ;

Example 3. In some embodiments, the DCI carrying the second signalingincludes a wake-up indication and/or a bandwidth part domain.

In some embodiments, some of the bandwidth domain indication informationincludes a BWP indicator and/or a bandwidth part state indication.

In some embodiments, the configuration information of the UE includeslocation information in the DCI.

In some embodiments, the UE monitors the DCI carrying the secondsignaling in a specific cell. The specific cell may be Pcell, PScell, orSpcell.

In some embodiments, the DCI carrying the second signaling includes awake-up indication field W(0)˜W(i+n−1), and a bandwidth part domainB(0)˜B(i+n−1), where i, n are non-negative integers.

In some embodiments, and as shown in the example of FIG. 3, the UEconfiguration information includes wakeup indication W(i) locationinformation in the DCI, and/or bandwidth part domain B(i) information inthe DCI.

In some embodiments, the wakeup indication is applicable to all servingcells of the UE, or the activated serving cell.

For example, as shown in Table 5, if W(i) is state 1 (eg, 1), then“awake” is indicated, whereas if W(i) is state 2 (eg, 0), then “do notwake up” is indicated.

In some embodiments, if W(i) indicates “no wake-up”, the UE may ignorethe corresponding bandwidth part domain.

In some embodiments, if W(i) indicates “no wake-up”, the correspondingbandwidth part domain is all 0s or all ones.

TABLE 5 W(i) Wake up indication Status 1 Wake Status 2 Not wake up

In some embodiments, B(i) characterizes a bandwidth part state.

For example, as shown in Table 6, B(i) is state 1 (for example, 1)indicating an “active state”, whereas if B(i) is state 2 (for example,0), it represents the dormant state.

In some embodiments, if the bandwidth part field indication informationincludes switching to the “dormant state” or switching to the dormantBWP, the indication information is not applied to the Pcell, or thePScell, or the Spcell, or the Scell configured with the PUCCH.

TABLE 6 B(i) Instructions Status 1 Active state Status 2 Dormant state
